As Germanwings co-pilot Andreaz Lubitz's past comes under the scanner after he apparently downed flight 4u9525 with 150 people on board, his former girlfriend has revealed chilling details about what went on in his mind.
Lubitz suffered from depression several years ago, and had even taken a break from training at Lufthansa after facing a burn-out syndrome.
But his former girlfriend told German newspaper Bild about the 'dark thoughts' that Lubitz had been harbouring and that he had planned a 'spectacular event' to ensure he was always remembered.
Lubitz had made an ominous prophecy to his former girlfriend last year.
"One day I will do something that will change the whole system, and then all will know my name and remember it," he had told her, according to the German newspaper.
"I never knew what he meant, but now it makes sense," she said.
The woman also revealed that she left Lubitz due to his 'erratic behaviour' and it has now come to light that the relationship ended just a day before the plane crash.
Given that the couple was planning to get married next year, the split may have troubled Lubitz to the extent that he decided to down the plane, a thought his former girlfriend revealed, used to give him nightmares.
The woman revealed that Lubitz often woke up screaming in the middle of the night.
"At night, he woke up and screamed: 'We're going down!', because he had nightmares. He knew how to hide from other people what was really going on inside," she told Bild.
The police who scanned Lubit's house in Dusseldorf, found a torn-up 'sick note' that he apparently hid from the airline because it would have debarred him from co-piloting the Germanwings flight 4u9525 that fateful day.
